Electrical Problems 2007 3325 Mahindra

[coal digger]

I checked battery, cables, post, and all fuses. Checked PTO safety switch. No lights, no gauges, after turning switch on. Replaced switch, starter relay, and timer. Still scratching me head on this one.

Not sure about your model (ie. all the safety switches) I assume you don't hear any clicks? I would lean towards a safety switch if the battery checked out, is there seat switch? ...clutch, pto, gears in neutral switch? Have you tried to bypass these safety switches?

 

[coal digger]

PTO and Neutral switches have continuity. No seat, no clutch switches. Haven't tried bypass. Still puzzled! Thanks for your help, much appreciated.

this wouldn't be a safety switch issue. Sounds to me like you have no juice going anywhere and missed a fuse in the main battery feed somewhere. Or a battery cable is busted or the connection of the ground cable to the tractor frame/engine or where ever it is attached is very ungood.

According to the Manual a separate fuse for a rotary pump solenoid is supplied and will not let the tractor start. I have searched for this fuse and cannot find it. A tractor mechanic told me it was close to the battery. Anybody KNOW where it is? Thanks!

If the OP has no power at all its probably a main fuse. Another Mahindra owner recently posted about the same problem. The cure was to remove the left side cover under the dash and the bad fuse was found in there. The OP replied to that thread but not sure he has the same no power problem or whether he checked that fuse. Sawduster2 posted pics of the location of the blown main fuse on his 3525.

 

[coal digger]

That is right. I found that 30amp fuse, it is still good. I'm thinking there must be a inline fuse somewhere in the wire harness. So for my head is still spinning.

Well I cleaned ground wire, and frame. Instrument panel lit up when I turned on the switch. The starter still would not turn over. When I turned on lights the instrument panel went plank. Still confused.

How about the ground strap to the frame?...So Battery to engine, engine to frame....

Maybe a missing ground connection. It usually is when things start to turn wierd like that.

 

[coal digger]

Ok,thanks very much to all. I will keep searching for solutions. Where would the ground strap be located?

Start at the negative terminal of the battery then look for straps connecting the frame to the engine block etc. All current flow requires complete positive and negative paths to the battery to work. You could use an Ohm meter with one end connected to the negative terminal of the battery to trace them from each circuit. A higher resistance reading in ohms is a problem.

Thanks again, all info. is much appreciated. This is like saddling a dead horse!

Bingo. When electrical gets weird, check the grounds.


And stop throwing parts at it. Get a test light AND a meter, and start TESTING your way from the battery toward the loads, and from the battery towards the grounds. You'll find the problem.

I would change the 30 amp fuse even though it looks good.

A simple continuity test will prove if fuse is good or bad....There is no in between!

Fuses ' can ' show continuity with a meter or old timey AA battery continuity light, and still fail to pass real current. Fuses can also be mechanically/electrically good one minute, and open the next, and visey versa. Old timey electrician, here... Emphasis on the ' old ' ....

That's what mine did till it blew. Power one day, not the next.

often times there have been tractors with pin connectors that are loose when clamped together, only way to test connectors is to buy a pin and test each individual pin connector

 

[melroebobcat]

let me clarify, we have found tractors manufactured in the last 2 years that have had loose connectors on main wiring harness and loose grounds on all different makes and models. the pins may appear there connecting when pushing male female ends together but there is enough room for the pins to vibrate causing all sorts of random electronic issues. I have seen new starters be bad from factory. I have seen a starter that was bad on a new unit due to moisture corrosion/ rust. good luck :thumbsup:
